Hey guys!
Here is my take on this test project.
The solution uses awesome Flow library that was created specifically for such tasks - concurrently processing data streams.
You may notice I don't use database at all. Yeah... I've read about database requirement kind of late 😅 and I think this solution is good enough. But if you'll insist on it, I can add database support: should be as easy as changing
File.stream!
withRepo.stream!
and adding some boilerplate code.P.S. I've also took liberty of rewriting test data generation to Elixir and make project structure more Elixir-ish in general. If you'd like to use it later I can make it a separate PR.
